Measuring positive and negative currents (bipolar operation): In applications
On 5-40Vdc powered (‘-DC1’), grounded-shunt models, the ammeter’s operating
designed to measure. This current enters TB-1 (-SHUNT), passes through the am-
meter’s built-in shunt and exits via TB1-2 (+SHUNT). For all models, this same full-
scale load current can also be routed, if the user so chooses, through TB2-1 and
TB2-2 (connection to positive rail of power supply). See detailed wiring diagrams.
where both positive and negative currents must be measured, Murata Power Solu-
tions recommends using ‘-DC4’ 8-36V isolated supply models. Negative current
fl ow is denoted by the illumination of the display’s negative (-) sign; the absence
of a negative sign implies positive current fl ow. Contact MPS if you have any ques-
tions regarding bipolar operation of DCA-20PC ammeters.
permissible as long as this overcurrent condition does not exceed 6 seconds and
occurs no more than once in a 60 second interval (10% duty cycle).
down voltage is tested with TB1-1 tied to TB1-2 (-SHUNT shorted to +SHUNT),
and TB2-1, TB2-2, and TB2-3 all tied together (+V shorted to -V). 500Vdc is then
applied between the two shorted terminal-block pairs; the maximum permissible
leakage current is 5uA.
on ‘-DC4’ models, and to TB1-1 (-SHUNT) and TB2-2 (+V) on ‘-DC1’ models. On
all models, TB2-1 and TB2-2 are internally tied together (+V). Operating supply
current is the current which powers the meter’s analog and digital circuits; it is
measured with zero load-current passing through the ammeter’s built-in shunt
(i.e., with the display reading “000” and one decimal point enabled).
supply current enters TB1-1 (-Shunt) but is not included in the displayed reading
(i.e., it does not pass through the built-in shunt).
